Today is the 29th IgNobel ceremony! You can watch it from the comfort of your home (or wherever you may be), or you can get there in time for the lectures this weekend.

Facebook follows you around, even when you’re not on Facebook. But fear not, now you can delete your history…well…sort of…ok, not really. Yikes.

Tomorrow: Lots of links from others on Friday the 13th! Stay tuned.
